Any decision with respect to the proposed partial demerger of Metso in which all assets and liabilities of Metso that relate to, or primarily serve, the Metso Minerals Business will transfer without liquidation of Metso to Outotec should be made solely on the basis of information contained in the actual notices to the Extraordinary General Meeting of Metso and Outotec, as applicable, and the Prospectus as well as on an independent analysis of the information contained therein. You should consult the Prospectus for more complete information about the Metso Minerals Business, Outotec, Outotec’s securities and the demerger.

No part of this release, nor the fact of its distribution, should form the basis of, or be relied on in connection with, any contract or commitment or investment decision whatsoever. The information contained in this release has not been independently verified. No representation, warranty or undertaking, expressed or implied, is made as to, and no reliance should be placed on, the fairness, accuracy, completeness or correctness of the information or the opinions contained herein. Neither Metso nor Outotec, nor any of their respective affiliates, advisors or representatives or any other person, shall have any liability whatsoever (in negligence or otherwise) for any loss however arising from any use of this release or its contents or otherwise arising in connection with this release. Each person must rely on their own examination and analysis of Metso, Outotec, their respective securities and the demerger, including the merits and risks involved. The transaction may have tax consequences for Metso shareholders, who should seek their own tax advice.

This release includes “forward-looking statements.” These statements may not be based on historical facts, but are statements about future expectations. Other forward-looking statements can be identified in the context in which the statements are made. Forward-looking statements are set forth in a number of places in this release, including wherever this release includes information on the future results, plans and expectations with regard to the combined company’s business, including its strategic plans and plans on growth and profitability, and the general economic conditions. These forward-looking statements are based on present plans, estimates, projections and expectations and are not guarantees of future performance. They are based on certain expectations, which may turn out to be incorrect. Such forward-looking statements are based on assumptions and are subject to various risks and uncertainties. Shareholders should not rely on these forward-looking statements. Numerous factors may cause the actual results of operations or financial condition of the combined company to differ materially from those expressed or implied in the forward-looking statements. Neither Metso nor Outotec, nor any of their respective affiliates, advisors or representatives or any other person undertakes any obligation to review or confirm or to release publicly any revisions to any forward-looking statements to reflect events that occur or circumstances that arise after the date of this release.

Outotec and Metso are Finnish companies. The transaction, including the information distributed in connection with the demerger and the related shareholder votes, is subject to disclosure, timing and procedural requirements applicable in Finland, which are different from those in the United States. The financial information included in this release has been prepared in accordance with IFRS, which may not be comparable to the financial statements or financial information applicable in the United States or by U.S. companies.

The new shares in Outotec have not been and will not be listed on a U.S. securities exchange or quoted on any inter-dealer quotation system in the United States. Neither Outotec nor Metso intends to take any action to facilitate a market in the new shares in Outotec in the United States.

The new shares in Outotec have not been approved or disapproved by the U.S. Securities and Exchange Commission, any state securities commission in the United States or any other regulatory authority in the United States, nor have any of the foregoing authorities passed comment upon, or endorsed the merit of, the demerger or the accuracy or the adequacy of this release. Any representation to the contrary is a criminal offence in the United States.

It may be difficult for U.S. shareholders of Metso to enforce their rights and any claim they may have arising under U.S. federal or state securities laws, since Outotec and Metso are located in Finland, and all or some of their officers and directors are residents of, non-U.S. jurisdictions. Judgements of U.S. courts are generally not enforceable in Finland. U.S. shareholders of Metso may not be able to sue Outotec or Metso or their respective officers and directors in a court in Finland for violations of the U.S. laws, including the federal securities laws, or at the least it may prove to be difficult to evidence such claims. Further, it may be difficult to compel Outotec or Metso and their affiliates to subject themselves to the jurisdiction of a U.S. court. In addition, there is substantial doubt as to the enforceability in Finland in original actions, or in actions for the enforcement of judgments of U.S. courts, based on the civil liability provisions of the U.S. federal securities laws.
